Abstract

L'invention concerne une bobine RF destinée à être utilisée comme antenne RF pour un système d'imagerie par résonance magnétique, pour émettre des signaux d'excitation RF et pour recevoir des signaux de relaxation de résonance magnétique. La bobine RF de l'invention comprend un réseau de pièces (1) qui sont couplées de façon capacitive les unes aux autres. Le réseau de pièces forme une surface résonante sur laquelle des courants de surface peuvent être excités par résonance pour générer au moins un mode de champ.
